Double Angle Strongback Plate
The safety factor to be applied to a particular product is a variable, depending on the degree of hazard or risk involved in the application of that product. In tilt-up construction various conditions can often increase the loadings as well as the degree of risk involved. Adhesion of the panel to the casting surface, jerking of the panel during lift, use of a crane not adequate for the job, bouncing of the wall panel after it has been lifted, handling the panel more than anticipated, transporting panel over rough surfaces, under or over booming, etc., all have high risk factors. Safety factors should be increased accordingly by the user to reduce these risks.
